If you want to feel under constant scrutiny and answer the many questions before being approved, even then the approval will be less that straight forward as your sign up will be put under scrutiny by the judicial committee that is the admin team. Beware though, if you do sign up be sure to use untraceable details of yourself because if they find any details as they conduct a snooping exercise on you that you have posted on any website deemed as "apostate" then you will be blocked from even the public view!
I had this happen to me but I can view the public forum again as I changed my ISP recently.
